Abstract:
|
The principal interest of the present investigation was to determine
seasonal and vertical variation of chemoorganotrophic utilisation of glucose
and sodium—acetate by the natural bacterial population in the aquaculture
pond of Narakkal, Cochin using techniques which allow maintenance of
the in situ gaseous concentrations during incubation. In addition salinity,
dissolved oxygen, temperature, hydrogen—ion—.concentration, primary production,
plant pigments and total bacterial concentration were determined
seasonally and vertically because of their possible relationship to chemoorganotrophy. |
